【8.028S 28mm Soft Dome Tweeter｜Delivers Clear, Transparent High-Frequency Reproduction】

This is the 8.028S 28mm soft dome tweeter, designed for those who want to emphasize high-frequency extension and a sense of transparency.

The tweeter’s diaphragm uses a newly developed 28mm Torcon soft dome diaphragm with lightweight construction, excellent internal damping, and heat resistance. With a wideband response from 940Hz to 25kHz, we aim for a clean, well-defined sound—from the smallest nuances in vocals to the lingering resonance of instruments.

It’s important that the high frequencies don’t just become brighter, but connect naturally within the overall music. The 8.028S is suited for those who want to bring out the initial attack and fine detail while also finishing the tweeter in a way that makes it less fatiguing to listen to, even on long drives.

For the magnetic circuit, it uses a lightweight 28mm voice coil and a high-grade neodymium magnet. The design also appropriately handles unwanted sounds generated on the rear side of the diaphragm to suppress harmonic distortion. In addition, by combining metal materials of different types, it reduces unwanted resonances and is designed with cooling performance in mind.

Because the mounting flange is unified in the same design as the 8.075, you can keep a cohesive look even when installing it side by side with the 8.075. This is a tweeter that’s easy to choose for those who want to build a system not only for sound quality, but also considering the post-installation design.

The impression of a tweeter changes depending on the mounting position and orientation, the speakers you pair with it, and adjustments to the crossover and volume. Even with the same 8.028S, by performing installation and tuning to match the vehicle and system, you can define the direction—whether you want vocals pushed forward, a wider soundstage, or a more natural presentation of fine details.

If you want to “make the high frequencies a bit cleaner,” “increase the amount of musical information by replacing the factory speakers,” or “build a setup that matches the design with the 8.075,” let’s think together about how the final result will sound, while checking your vehicle and current system.
